and from this rock comes the almost complete specimen of ^^^^^ 



Blapsium Egertoni. Lihelhila may also be noticed from the 



Purbeck Beds and from the Bagshot Beds of Upper Eocene 



age near Bournemouth. These last-mentioned beds, as well 



as the Oligocene Bembridge Beds of Gurnet Bay in the 



Isle of Wight, have furnished a number of insects belonging 



to many modern families. 



Among the fossil insects from foreign localities we Wall-case 

 notice first some Orthoptera allied to the cockroaches, and 

 some large I^europtera, from the Coal Measures of Com- 

 mentry, AUier, France; a locality famous for the beautiful 

 examples that it has yielded. The next series of importance 

 is that from the Lithographic Stone of Solenhofen; here

we may imagine that numerous insects lived on the islands 

 around a lagoon, into whose placid waters they were 

 constantly being blown. The Orthoptera are represented 

 by the cricket Pseudogryllacris [Gryllacris], by the locust 

 Pycnophlchia, and by Ghresmoda \Fygolampis] ohsm^xi, a 

 precursor of the Mantidae and Phasmatidae or stick-insects. 

 Among the N"europtera is the dragon-lly Cymatoplilchia. 

 Water-bugs allied to Nepa and Bdostoma represent the 

 Hemiptera. Beetles are numerous. The chief example of 

 the Hymenoptera is Pseudosirex, one of the tailed wasps 

 that bore into trees. Cretaceous insects are unrepresented, 

 but there are a number from Tertiary rocks, all of modern 

 type. The Oligocene deposits of Aix in Provence and of 

 Florissant in Colorado, the Miocene Beds of Oeningen on
